Default Does software or hardware determine a modem?

Hello, I have a Sim unlocked bell Canada note 3 and an planning to rent/borrow a NTT Docomo Sim card from a friend in Japan for use while on a trip in Japan.

I have a stock firmware and modem and am wondering if I can flash another modem to gain access to the NTT Docomo spectrums because right now as is my phone will only be and to access the UMTS 2100 spectrum.

Technical info
Bell Canada stock note3
LTE: 700/850/AWS/1900/2100/2600
HSPA/UMTS: 850/1900/2100/AWS

NTT Docomo spectrum
LTE: 1700/1500/800/2000
UMTS: 2100/800

If any of my facts are incorrect please advise.
Thank you.

SM-N9005 variants have completely same hardware but different software (firmware)
so if u have problem with modem u should flash another rom that 1. compatible with ur device (for N9005) 2. compatible with region.

I am not entirely convinced that is a good idea - modem files are now notoriously difficult to write with Odin on Qualcomm devices. You should also look into the US threads where I believe there are sensible bounties for making one model of phone to work on the frequency of some other carrier, and none of those being claimed should suggest things are far from simple.
